Fetal Circulation

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Area of Science:

Biomedical Engineering
Neonatal Physiology
Dynamical Systems Theory

Background:

Low umbilical artery pH indicates neonatal acidosis, increasing complication risks.
Phase-rectified signal averaging (PRSA) shows promise in fetal heart rate analysis but is parameter-sensitive.
Current PRSA parameter selection relies on empirical methods or grid searches.

Purpose of the Study:

To investigate the phase-rectified signal averaging (PRSA) method using dynamical systems theory.
To reveal the connection between state space reconstruction and PRSA.
To introduce a novel feature for improved dynamical system characterization in fetal heart rate analysis.

Main Methods:

Analysis of PRSA through the lens of dynamical systems theory.
Exploration of the relationship between state space reconstruction and PRSA.
Development and testing of a new feature for dynamical system characterization.
Experimental validation on an open-access intrapartum Cardiotocography database.

Main Results:

A novel intrinsic connection between state space reconstruction and PRSA was identified.
The proposed feature demonstrates superior characterization of dynamical systems compared to PRSA.
Experimental results show the new feature outperforms state-of-the-art PRSA in pH-based fetal heart rate analysis.

Conclusions:

The new feature offers improved performance over PRSA for fetal heart rate analysis.
This approach provides a more robust method for assessing neonatal acidosis risk.
Dynamical systems theory offers valuable insights into signal processing techniques like PRSA.
